SLICING AND SAWING DEVICE.

Application filed November ['0 all w/icm' it may worm r11 Be it knownthat l, llnn. E. EHRLICH, a citizen of the lhi'ited States. residing at("itrus Park. in the county of llillsborough a d State of Florida, haveinvented a certain new and useful Improvement in Slicing and SawingDevices, of which the following is a full, cl 'ar, cont-isefand exactdescription, reference being had to the accompanyin drawings, forniingapart of this specification.

The invention relates to slicing and sawin devices, and has for itsobject the production of a unitary arrangement whereby it; either aknife or saw edge may be presented to the material, the character of thematerial to he cut determining which appliance is to be used, to severthe slice. from the piece from which it is cut.

The invention has as a further object the provision of a simple andetieetive construction whereby either of the above named appliances maybe brought into position to result. in the accomplislnnent of thedesired end. and which is capable of operation in culillllltfllOli witha suitable driving mechanism, as for instance. such as shown anddescribed in my application Serial No.

' 19.31337. filed November 27, 1916, which perit n'iits the saw or knifeto be reciprocated and properly positioned to cause the cutting orsewing to be accomplished,

The invention further contemplates the provision of a means to controlthe reciprotlti cation of the saw or knife, this means being appliednear the handle of the device where it will be readily accessible. Allof these features together with others will be more readily apparentfrom av detailed description of one form of carrying out. my inventionwhich is shown in the accompanying drawings, in which I Figure 1 is a.side elevation of the invention showing the knife or saw frame in one.

a of its ext renic positions of reciprocation;

Fig. 2 is a section taken on line 2-2 of Fig. 1, showing a means forcausing the knife or saw edge of the blade to be presented to thematerial; and

Fig. 3 a fragmental view similar to that shown inv Fig. 1, showing theparts in alter nated position.

The embodiment of the. invention shown. in the drawings contemplates theuse of a saw frame It) having the blade 11, the opposite edges of theblade being provided with Specification of Letters Patent.

the saw teeth 12 and the knife edge This saw frame 10 is mounted uponthe frame ll having the handle 15. .The frames 10 and 1% are connectedtogether by the pins 16 and 17 which are passed through the slots 18 and19 of the frame 10 and into the frame 14 holding these parts together.Upon the upper part of the frame 10 is mounted the tread 20 with whichcooperates the segmental tread or driver 21 which is actuated back andforth by the crank and the link 23 connecting the segment and the crank.This crank 22 is driven by the flexible shaft 24. By this arrangement itcan readily be seen that as the crank 22 is rotated the frame 10 havingthe blade 11 will be reciprocated and will either saw or slice thematerial depending upon which the edges of the blade 11 are presentedthereto. The frame 14 and its associated parts are suspended from the.hanger 25 which may be raised and lowered as described in my applicationSerial No. 133,637. This frame It and its associated parts are alsopivotally connected to the hanger '25 by the link 26 which is pivotedthereto at 27. The link has its oppositcen di secured to the frame H.and by virtue of its pivotal connection with the hanger, the frame ispermitted to assume variousangular positions. :By the arrangement jllStdO- scribed the saw or knife frame may be reciprocated, raised andlowered, and shifted to various angular positions from the horizontaland vertical. This provides for the various positions which a device ofthis character may be. subjected to.

- The means whereby the blade 11 is rotated to present either edgethereof "to the material to be cut includes a lever 21) which is pivotedat 30. The forward endol the lever extends beyond the rear end of theframe 10 when this frame assumes its extreme position in this direction;The opposite cnd of the lever extends downwardly and provided with theportion 31 which forms a handle. This portion extends beyond the handhole 32 and-is accessible to be grasped by the operator to manipulatethe shifting mechanism which operates the blade 105 11. The saw frame 10nearest the handle 15 has mounted upon it. the bar 33 which is securedto the frame by the screw 34 which operates in the slot 35. This bar 33is further provided with the pin 36 having one end of 'a spring 37secured to it. The other end of this spring is secured to the screw e5whieh causes the blatle l l to he shit'tett.
